I find I obsess about stuff, but usually the feature either doesn't live up to the hype or is so much worse.  Right now I'm studying the big drop on C4 in Vietnam. I watch videos on YouTube saying I'm learning, but I'm really just driving myself crazy. I completely understand the strange effect of being on and off some days/rides and the resulting ease of some features. I just wish I was more consistent. Sometimes all it takes is finding a trail system that consistently challenges you. That's what Vietnam did for me.
